Criticizing someone for making an error … while making the same error yourself

That’s another concept that I’m sure must have an eighteen-syllable descriptor in German but doesn’t have a matching name in English. David Friedman has a great illustration of this in the criticism of a nineteenth century anthropologist by Stephen Jay Gould:

The late Stephen Jay Gould was both an evolutionary biologist and a popular essayist. In the book The Mismeasure of Man he argued that scientists unconsciously manipulate their data to fit their preexisting prejudices. As evidence he cited the work of Samuel George Morton, a 19th century physical anthropologist who assembled a large collection of skulls from many parts of the world and measured their cranial capacity in an attempt to answer questions about racial differences. According to Gould, Morton skewed his data in various ways to fit his racial beliefs.

I have just read an article by a group of modern anthropologists who went over Morton’s data and remeasured many of the skulls that Morton measured — something Gould did not do. The authors concluded that most of Gould’s criticisms were poorly supported or falsified. The errors that Gould reported in Morton’s analysis resulted from errors by Gould, not by Morton. Morton did make some mistakes in his work, but they were in the opposite direction from his biases.

[…]

The obvious conclusion, not stated by the authors of the article, is that Gould’s central claim was correct. Scientists sometimes bias their work to fit their preconceptions. As Gould demonstrated by doing so.
